You aren't typing a letter, you are typing source code. You make a mistake in a letter, nobody cares and few notice it. You make a mistake in your source code, and compile, you have to go hunting for that bug.
Sure I worked with programmers that did 60wpms, I always had to help them find the errors in their source code. I always had to take time away from what I do to help them. I type with just two fingers like Scotty from Star Trek, but I debug better and write a better quality code.
